The steam generator pressure controller is used to control the generator, because it has no water level display, no board control, and its heating control is mainly controlled by the floating water level controller. Henan Gas fired hot blast stove When the water level is moderate, the floating point is connected to the control voltage to operate and heat the AC contactor. The generator has a simple structure and is currently used in the market. The common non heating fault of this generator is mainly found in the float level controller. First check the external wiring of the float level controller, connect the upper and lower control lines, and then remove the float level controller to see if it is flexible. small-scale Gas fired hot blast stove factory You can use the manual to use the meter to determine whether the upper control point and the lower control point can be connected. Check the equipment and check for water. The float can fill the fuel tank, replace the float, and eliminate faults.

The waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Henan Gas fired hot blast stove In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. small-scale Gas fired hot blast stove factory Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Henan Gas fired hot blast stove Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. small-scale Gas fired hot blast stove factory Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

Most people may already know something about flue gas waste heat recovery, because they have already explained a lot about it. In order to let you know the relevant knowledge of flue gas waste heat recovery, the following is a brief introduction to the two methods commonly used for recovery. Henan Gas fired hot blast stove Two methods are usually adopted for flue gas waste heat recovery: one is to preheat the workpiece; The other is to preheat air for combustion support. The flue gas preheating workpiece needs to occupy a large volume for heat exchange, which is often limited by the operation site (this method cannot be used for furnaces that are used intermittently). small-scale Gas fired hot blast stove factory Preheating air for combustion support is a good method. It is generally configured on the heating furnace, which can also strengthen combustion, speed up the temperature rise of the furnace, and improve the thermal performance of the furnace. This can not only meet the requirements of the process, but also achieve significant comprehensive energy-saving effect.

The produced waste heat boiler for hazardous waste incineration is a natural circulation water tube boiler, which adopts a single drum vertical layout and a full membrane water wall structure. Henan Gas fired hot blast stove The surrounding, top and three middle membrane water-cooled walls form a tight series of heat exchange flues. The convection heating surface is no longer arranged inside the heat exchange flue, and radiation heat exchange is adopted, so as to ensure the smooth flow of high-temperature flue gas containing strong coking adhesive ash in the heat exchange flue. Full automatic shock soot blower is arranged on the membrane water wall, and inspection holes and observation holes are reserved. small-scale Gas fired hot blast stove factory The bottom of the boiler is composed of membrane water walls on both sides to form a water-cooled ash bucket, and the lower part is connected with a closed spiral ash extractor. The settled soot in the waste heat boiler and the ash removed by the soot blower are discharged out of the boiler by the ash extractor. The furnace wall is of pipe laying structure, and the outside is covered with corrugated steel plate.

The steam used in the steam generator of the hotel laundry is usually 0.4~0.6MPa saturated steam. The working temperature of steam is not very high. Henan Gas fired hot blast stove The steam boiler of the hotel requires high steam efficiency due to operating costs, so it can save operating costs. The area of the hotel is relatively limited, so the steam boiler with small floor area must be selected. In order to control the investment cost and heat loss of the steam pipe, the steam boiler is usually placed on the side of the laundry room. small-scale Gas fired hot blast stove factory The steam equipment in the hotel laundry room can only be turned on when washing, not when washing. Therefore, the steam generator is required to start steam production quickly. Laundry equipment is sometimes opened a lot and sometimes less, so the steam boiler is required to adjust the steam volume within the specified range.
